HAT-PIN.

Specification of Letters Patent.

Application filed September 30, 1911.

Patented Aug. 12,1913. serial No. 652,132.

To all whom, t may concern:

Be it known that I, ALEXANDER B. KoKnR- NOT, a citizen of the UnitedStates, residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented a new l and useful Hat-Pin, of which thefollowing is a specification.

This invention has reference to improvements in hat pins, and itsobjectis to provide a hat pin which may be securely fastened to a hatwith the point interior to the body of t-he hat or projectingtherethrough for a short distance at the will of the operator. To thisend the hat pin comprises a head member and a shank member with theshank member capable of telescoping for an appropriate distance intothehead member but having a normal tendency to project therefrom to thefull vextent provided. Locking or retaining means on the shank membercoacting with other locking or retaining means on the head member permitthe setting of the shank member so that it will project from the headmember to any desired ext-ent within the range of telescoping movementof the shank member into the head member whereby the shank member may beintroduced through one side of the hat body toward the other sidethereof, so that the point of the pin will engage the other side of thehat member while the butt end of the shank of the pin will relativelymove into the head member as the latter is brought into engagement withthe corresponding portion of the body of the hat for being securedthereto, provision being made for such securing or fastening of the headmember to the hat body. If, however, it be desired to have the point endof the pin shank pierce the side of the hat body remote from that towhich the head end of the pin is secured, then the pin shank may becaused to project from the head member an appropriate distance, so thatthe point will pierce the corresponding side of the hat body, but theeX- tent of projection of the pointed end of the pin shank is readilydetermined by the operator, and the pin shank may be locked lagainstfurther movement of the shank through the hat body.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawings forming a part of this specification, with the understanding,however, that while in the drawings there are shown a number ofpractical forms of the invention, the latter is susceptible of other'practical embodiments ywithin the scope of the claims and consequentlyis subject to changes and modications so long as the salient features ofthe invention are retained.

In the drawings Figure 1 is an elevation of one form of hat pin inposition in a hat, which latter is conventionally shown and illustratedin diametric section. Fig. 2 is a longitudinal section of the headmember of the hat pin shown in Fig. 1 with the shank of the pin inelevation. Fig. 3 is a section on the line 3 3 of Fig. 2.

Fig. 17 is a section on the line 17-17 of Fig. 16 withdistant parts omitted. Fig. 1S is a perspective view of the latch membercarried by t-he butt end of the pin shank in the structure shown inFigs. 15 and 16. Fig. 19 is a plan view of the butt end of the pin shankof the structure shown in Figs. 15 and 16. Fig. 20 is a view kofasomewhat diiferent form of latch member for use in a structure similarto that of Figs. 15 and 16.

In the drawings there is shown a pin provided with a head 1 and a shank2, the latter entering the head through an axial perforation 3 in oneend of the head and at the end remote from that entering the head thepin is provided with a point indicated at 4. i

The head is provided with an internal axial bore 5 extending from theend of the head remote from the'passage l toward but terminating shortof the end of the head receiving the shank of the pin. is of greaterdiameterl than the shank of the pin, and the latter at its butt end hasa block or enlargement 6 of a size to snugly yet freely fit within thebore of the head. On opposite sides the inner wall of the bore of thepin is provlidedV with longitudinal grooves T, and the block 6 isprovided with oppositely directed splines or tongues 8 adapted to thegrooves 7, so that the block 6 may move along the bore of the head ofthe pin without turning, being guided by the tongues 8 engaging in thegrooves T. On opposite sides of the head of the pin is a longitudinalslot 9, which, in the structure shown in Figs. 2 and S, is duplicated onthe diametrically opposite side of the head of the pin, as indicated at9@ in the two figures referred to, and the slot 9, and when present theslot 9a, are disposed in radial planes substantially perpendicular tothe plane of the grooves 7.

In the structure shown in Figs. 2 and 8 the side walls of the slots 9and 9rb are forined with forwardly directed notches 10 opening at theouter edge of each wall of the respective slot and terminating short ofthe inner edge of the slot, these notches eX- panding from their innerends toward their outer ends.

Applied to the end of the block 6 remote from the pin shank 2 is a plate11 having oppositely directed arms 12 projecting therefrom in the planeof the plate, and these arms terminate in expanded fingers 13 returnedon the arms, and at the returned ends the ngers are tapered tosubstantiallyT a point as indicated at 11. The disk 11, together withthe arms 12 and lingers 13, may be made of some material which will-bendreadily without breaking, certain of the metals being capable of suchmanipulation. The disk 11 is of a size approximately that of the end ofthe block (5 remote from the shank 2 and may be soldered or otherwisesecured thereto, while the arms 12 are each of a length to permit themto extend through the slots 9 and 9 to the exterior thereof with thepointed ends 1st outside the body of the head l. The slots 9 and 9 openat the end of the head remote from the passage 3 and the pin with theblock 6 and disk l1 and parts carried thereby may all be readily in`troduced through the then open end of the head. The block G is engagedby a spring 15 housed within the head and confinedj therein inengagement at one end with the plate 11, and at the other end with ascrew plug 1G, which maybe formed with a flange 17 adapted to overridethe open end of the slots 9 and to form closures therefor.

This bore` At the end of the head 1 traversed by the passage 8 there issecured a plate 18 having at opposite sides projecting prongs 19, theseprongs being each given a forward twist, so that when brought intoengagement with a hat body, such as indicated at 2O in Fig. 1, theprongs by a rotative movement of the head 1 may be caused to enter thehat body and lock therein. The form shown in F ig. 8 is in the mainsubstantially the same as the form shown in l? ig. 2, and, therefore, Fig 8 is in .most respects a plan view of the same form that isillustrated in Fig. 2 in longitudinal section. The form shown in Fig. 8,however, differs in that the plug 16a is in some respects slightlydifferent in form from the plug 1G of Fig. 2 in that the flange 17 isomitted and the corresponding end of the head is surrounded by a bandseparate from the plug, while the plate 182L corresponding to the plate18 of F ig. 2 is formed with a flange 21 concentric with thelongitudinal axis of the head 1, so as to receive a portion of the endthereof in which the passage 3 is formed.

When it is desired to use the hat pin, the shank 2 is pushed into thehead 1 and the force used for this purpose tends to move the points 14,which in Fig. 2 are shown as lodged in the foremost recesses 10, out ofsaid recesses, the metal of the arms 12 readily yielding to the forceapplied, and this metal being flexible but not elastic will hold theposition to` which it is moved. The pressure upon the shank 2 tending tomove the shank into the head 1 is under the conditions assumedsuiiicient to compress the spring 15 so that the shank 2 is moved intothe head 1, or the latter moved along the shank 2, as the case may be,to the desired point, when the user may press upon the lingers 13)k toforce the points. 1/-1 into their recesses 10 then in their path, andthe shank is thereby locked against reprojection, when the force tendingto telescope the pin shank with relation to the head has been removed.

By holding the fingers 13 in the engaged position with respect to thenotches 10 whereby the projection of the shank of the pin is determined,the pin may be inserted into the body of the hat 2O in the usual mannerand ultimately the prongs or spurs 19 are brought into engagement Vwiththe body of the hat when a twisting movement of the head of the pin willcause the prongs to enter the body of the hat and so lock the head tothe hat without further mechanism, the shape and position of the prongsbeing such that there is no liability of the prongs loosening andpermitting the pin to like wise become loosened.

ldlhere it is desirable that the point of the pin shall not pierce thatwall of the hat remote from the wall entered by the pin shank, it ispreferable to line the hat body with cork or some other like material,indicated at 22 in Fig.' 1, and to hold the hat body to its normal shapeagainst any tendency of the pressure of the pin to distort the hat bodyit is preferred to introduce between the lining 22 and the ordinary band23 on the inner wall of the hat, a strip or ring 24 of metal or otherstiff material.

Should it be desired to use the pin with a hat unprovided with thelining designed to receive the point of the pin, the shank of the pinmay be allowed to project to a greater extent from the head than in thecase first considered, and the point may then pierce the wall of the hatremote from that first entered by the pin shank, but the extent ofprojection is readily determined by locking the shank of the pin to thehead in appropriate ones of the recesses 10 in the manner alreadydescribed. l/Vhen it is desired to lengthen or shorten the effectivelength of the pin shank a force tending to telescope the pin shank intothe head will at once release the fingers 13 from engagement with therecesses 10 in the manner already described.

Instead of the locking means shown in Figs. 1 and 8 a different form oflocking means such as shown in Figs. 9 and 10 may be employed. In thiscase the slot 9 only is provided and the outer edges of the walls ofthis slot are formed with sockets 25 with a socket in one wall of theslot coacting with a like socket in the opposite wall of the slot toform a pocket for the reception of a ball or lmob 26 on the free end kofan arm 27 hinged, as indicated at 28, to the block 6 at the butt end ofthe shank 2. The knob 26 readily engages in any pair of recesses orsockets 25 into which it is moved and the block 6, together with theshank 2, is locked against further movement under the action of thespring 15. The movement of the knob 26 out of the locking sockets isreadily accomplished by a force acting on the shank 2 tending tocompress the spring 15, and if the pin be held in a position where theknob is uppermost, the latter will drop by gravity into any pair ofsockets into coincidence with which it may be moved.

In the structure shown in Figs. 12, 13 and 14 the parts of the pin arethe same as in the preceding figures with the exception of the lockingmechanism. In the form shown in Figs. 12 to 14 the block 6 is providedwith a radial extension 29 projecting through the slot 9, while thewalls of the slot are formed with recesses 10a inclined like therecesses 10 and pivoted to the free end of the extension 29 at a pointbeyond the outer wall of the head 1 is a pawl 30 having an expandedtooth or free end 31. This pawl is drawn toward the block 6 by a spring32 and a knob Furthermore, the extension 29 is provided with lmobs 34 orother suitable means whereby the block may be moved from point 'to pointalong the head without the necessity of grasping the shank 2. The spring32 tends to seat Ithe pawl tooth 31 in appropriate pairs ofnotches 10aso as to lock the pin shank 2 and block 6 against the action of thespring 15.

In the structure shown in Figs. 15 to 19 and in somewhat modified formin Fig. 20 the parts of the pin agree in general with those of the otherfigures with the exception of the locking means. The slot 9 is provided.With a series of recesses 35 in one wall only, the closed ends of theserecesses being directed toward the point of the pin.v The block 6 hasone end formed with a groove 36 in the form of an advancingrspiral, andadapted to this groove is a band 37 also in the form of an advancingspiralwith the free ends overlapping, and from one side there projectsan arm 38 terminating in a ball or knob 39. The arm 38 is of sufficientlength to extend through the slot 9 when the band 37 has been engaged inthe groove 36, and between one end of the band 37, such end beingindicated at 40, and the inner termination of the groove 36, indicatedat 41 in Figs. 17 and 19, there is lodged a spring 42 tending to `movethe band 37 in the unwinding direction with relation to the groove 36,

the action of the spring 42 tending at all Y times to move the arm 38into an appropriate one of the notches 35, from which notch the arm maybe removed by a suitable force applied to the knob 39, said force beingsuilicient to compress the spring 42.

An operator grasping the knob 39 may move the band 37 in a direction tocarry the arm 38 out of a notch 35 when the block 6 and the pin shank 2may be readily moved along the head to any desired position, compressingor releasing the spring 15 in accordance -with the position from whichthe knob is moved.

The structure sho-wn in Fig. 20 dii'ers from that shown in Figs. 15 to19 only in that there is provided a band 43 in the form of an incompletering lodged in a partially circular groove in the block 6 with aninterposed spring 4-4. The structure shown in Fig. 2 is in operation thesame as the structure shown in Figs. 15 to 19, but usually the structureshown in Figs. 15 to 19 is to be preferred, because of ease ofmanufacture and assembling.

The several forms illustrated and described are deemed sufficient toshow the comparatively wide range of practical embodiments of thepresent invention. In all the several forms the pin shank and head arein telescoping relation with the head containing a spring tending toproject the pin locking means for holding the pin shank and head Wit-hthe shank projecting to a less extent than its full extent ofprojection, but which locking means will readily yield to a forcetending to further telescope the pin shank into the head, thetelescoping movement oi" the pin shank being in all the forms in a rightline coincident with the longitudinal axis ot' the head and Without anytvvisting action,

While in Fig. l the cork lining 22 is shown as. meeting the ring 24, itWill be understood that a free space may be left between the lining andring, so that the pin may be inserted through the Wall of the hatwithout necessarily piercing the cork lining While the pointed end ofthe pin shank may be made to engage the inner Wall of the cork lining onthe side of the hat opposite to that Where the pin shank is inserted.
